When the snow thickness detection data is inaccurate or not timely, a series of problems such as increased workload of equipment such as snow remover, reduced working efficiency, increased snow removing cost, untimely snow removing, tired personnel, reduced runway safety efficiency, prolonged runway downtime, reduced flight punctual rate and the like can be caused.
The detection of the snow cover artificial ruler of the airport pavement or the experience judgment of snow removing personnel has great defects. In the daytime, the runway utilization rate is high, particularly, the average arrival and departure rate is high in a large international airport, workers cannot go to the road at will for detection, and the detection of a manual ruler is impractical; the reliability is low because the experience judgment is influenced by the observation distance and personal experience. At night, a series of problems such as untimely detection exist in manual ruler detection and experience judgment of snow removing personnel, multiple times of up-road detection are needed, detection is inaccurate in snowfall period, a detection result can only represent the snow thickness at the detection moment, the length of a common runway reaches 3.6 km, the number of detection points is limited, the problem of data limitation exists, and accurate judgment on the snow thickness of the whole runway is difficult.
Because the structure of the airfield runway is special, as shown in fig. 3, the middle of the road is high, the two sides of the road are low, the road is affected by the running of the aircraft, snow generally presents the characteristics of thinness in the middle and thickness on the two sides, the automatic detection means for measuring the thickness of snow on the general horizontal road cannot be realized, and the means for detecting on the general horizontal road are generally equipment for collecting the condition of the wider road at a high place, while under the special environment of the airfield runway, the shoulder equipment of the airfield runway has the installation standard requirement, the height cannot be higher, so that the existing measurement means on the horizontal road are expected to be used for the airfield runway to have technical obstacle.

Referring to fig. 2, based on the hardware device of the foregoing embodiment, an embodiment of the present application provides a method for obtaining an airport runway snow thickness, including the following steps:
s00: according to the section center line of the airfield runway, dividing the airfield runway to obtain two runway half areas symmetrical about the section center line.
In the implementation process, the section of the airfield runway is shown as figure 3 and has a symmetrical structure, so that the measurement can be divided into two runway half areas symmetrically by a central line, as shown in figures 4 and 5, the two runway half areas realize full coverage of the whole runway, and the measurement effect is improved.
S10: respectively acquiring the actual distance between a measuring point and the snow surface on the nearest runway half area under a plurality of preset angles; the runway semi-area is obtained by dividing the airport runway according to the central line of the section of the airport runway, a plurality of preset angles are respectively obtained based on a plurality of prefabricated points, the plurality of prefabricated points are arranged on the surface of the runway semi-area, the prefabricated points on the same runway semi-area are located on the same virtual arc, and the depth of the virtual arc is equal to the width of the runway semi-area.
In the implementation process, the measurement point is the point where the distance measuring equipment such as a laser distance meter is located, usually the point where the laser emits, and the position of the measurement point can be set as shown in fig. 4; the distribution of the prefabricated points is shown in fig. 5, the angle of depression and the horizontal angle of the laser range finder are matched to calibrate each prefabricated point, namely, under the condition of no snow coverage, the angle of adjustment enables the range finding equipment to sequentially measure the distance between the distance measuring equipment and the prefabricated points at the measuring points, certain fixed values are recorded, the angle of depression and the horizontal angle of each prefabricated point are used as preset angles, and the relative distance is obtained and used for subsequent calculation, and the figure 7 is a schematic diagram of measuring the prefabricated points under the condition of no snow.
Due to the existence of the preset angle, the position of the prefabricated point can be expressed as the corresponding preset angle under the condition of snow, the distance measuring equipment can obtain the actual distance between the measuring point and the snow surface on the nearest runway half area only by measuring the measuring point according to the preset angle, and the actual distance is the distance to the prefabricated point, which can be detected by the measuring point under the condition of snow coverage, as shown in fig. 8, the distance to the prefabricated point is measured under the condition of snow.
As the measuring points are arranged according to the runway half area and are respectively arranged on two sides of the runway, as shown in the figure 5, the measuring points can be symmetrically arranged on two sides of the runway, can be alternatively arranged, or are arranged in a plurality of the measuring points along the extending direction of the runway, but the purpose is the same, so that the measuring range of the distance measuring equipment can cover the width of the runway half area, namely, the measuring points are distributed according to the arc shape in order to match with the runway with arc shape change, namely, the measuring points on the measuring points are positioned on the same virtual arc on the same runway half area, the depth of the arc is equal to the width of the runway half area, and a group of relative measuring points can just realize full coverage of the whole runway width. As for the length direction of the runway, as the snow is uniform in the length direction, a part of the runway can be flexibly set according to service requirements, and can be used as a measurement basis, a plurality of measurement points can be arranged along the runway, corresponding prefabricated points are also arranged corresponding to each measurement point by adopting the means, the more the prefabricated points are, the higher the measurement accuracy is, and the prefabricated points can be uniformly distributed along the virtual circular arcs, so that the uniform full coverage of the measurement data to the width direction of the runway is ensured.
S20: obtaining the snow thickness of a plurality of prefabricated points according to the first relative distance, the second relative distance, the preset angle and the actual distance; the first relative distance is the relative distance between the measuring point and the airfield runway, and the second relative distance is the relative distance between the measuring point and the prefabricated point.
In the implementation, as shown in fig. 8, the relative distance between the measuring point and the airfield runway includes: measuring the horizontal distance d of the point from the boundary of the airport runway and the vertical distance H of the point from the boundary of the airport runway; since the horizontal angle does not participate in the calculation when measured at a single prefabricated point, the preset angle here includes only: measuring the depression angle theta 1 of the point; the distance between the measuring point and the prefabricated point is L; the actual distance is then L1, and the aim is to obtain the snow thickness H1 of the prefabricated spot.
Specifically, according to the first relative distance, the second relative distance, the preset angle and the actual distance, the snow thickness of a plurality of prefabricated points is obtained, including:
according to the horizontal distance between the measuring point and the boundary of the airport runway, the vertical distance between the measuring point and the boundary of the airport runway, the preset angle, the second relative distance and the actual distance, the snow thickness of a plurality of prefabricated points is calculated by adopting the following formula:
wherein H1 is the snow thickness of the prefabricated point, L is the distance between the measuring point and the prefabricated point, L1 is the actual distance, H is the vertical distance between the measuring point and the boundary line of the airport runway, d is the horizontal distance between the measuring point and the boundary line of the airport runway, and theta 1 is the depression angle of the measuring point.
In the specific implementation process, after the structural schematic diagram in the measurement shown in fig. 8 is converted into a line relation, as shown in fig. 9, H2 and L2 can be calculated, where:
according to the similarity theorem, it is possible to obtain:
the above equation is modified in conjunction with the above calculation equation, namely:
in the above formula, L, L, H, d and θ1 are all known amounts, and H1, that is, the snow thickness of the prefabricated spot can be calculated.
S30: and obtaining the snow thickness of the airfield runway according to the target demand and the snow thickness of the prefabricated points.
In the implementation process, the target requirement is a data requirement formulated by an airport according to the requirement, and because the runway of the airport is not horizontal and the road monitoring requirement of the airport is different from that of a common roadside, the snow condition of which road section is output or the snow condition of each position in the longitudinal direction of the runway can be specified under the normal condition so as to guide the snow cleaning work.
In one embodiment, the method for obtaining the snow thickness of the airfield runway according to the target demand and the snow thickness of the prefabricated spot comprises the following steps:
dividing the strips in the width direction of the airport runway and parallel to the central line of the airport runway to obtain a plurality of parallel strips.
In the specific implementation process, the snow accumulation condition in the length direction of the runway is generally uniform, so that targets are required to be formulated in the width direction of the runway, the runway is divided into a plurality of parallel strips in the width direction according to the requirements, and the snow accumulation data of the runway are more visual and real; the more stripes are divided, the closer the output data is to the true value, as shown in fig. 6, which is the case of dividing into five stripes.
A target strip of the airport runway is determined from the strips according to the target demand.
In the specific implementation process, in the case of dividing the strips in this embodiment, the target needs to obtain the snow thickness on the target strip of the airport runway, that is, the snow condition of one of all the strips or multiple strips needs to be specified to be output.
And obtaining the snow thickness of all prefabricated points on the target strip according to the target requirement of obtaining the snow thickness on the target strip of the airport runway.
And obtaining the snow thickness of the target strip of the airfield runway according to the average value of the snow thickness of all the prefabricated points on the target strip.
In the specific implementation process, due to the structural characteristics of the airport runway, the thickness of the snow is gradually changed in the width direction, and in order to determine that a representative value can represent the snow condition in the whole strip, the data of the snow thickness of all the prefabricated points in the strip are extracted firstly, and then all the values are averaged to be used as the snow thickness of the strip where the representative value is located.
According to the section characteristics of the airport runway, the airport runway is divided into two symmetrical runway half areas according to the central line of the runway to be measured, and the prefabricated points on the same virtual arc are arranged, so that on one hand, the prefabricated points can be matched with the measuring points to determine different corners, on the other hand, the depth of the virtual arc is equal to the width of the runway half areas, the full coverage of the width of the runway can be realized, and the snow accumulation condition of the whole runway with different thickness conditions can be effectively reflected by the data measured by the prefabricated points; because the prefabricated points are arranged on the runway half area in advance, under the cooperation of the prefabricated points, the snow thickness is measured, the distance from the measurement point to the snow surface at the prefabricated points can be obtained only by measuring the snow thickness at the prefabricated points according to the preset angle, and then the snow thickness condition corresponding to each prefabricated point can be rapidly and accurately obtained according to the existing distance information, so that the timeliness of manual ruler measurement is poor, the snow thickness condition of each part in the runway width direction can be mastered in real time, the detection accuracy of the snow thickness on the airport runway is improved, and finally the snow thickness of the airport runway is represented according to the actual demand output.

The method has the advantages of high data authenticity, long distance, high ranging precision, strong anti-interference performance and high detection instantaneity, and does not need to stop the navigation and go up the road for detection.
As shown in fig. 5, taking a runway width of 45 meters as an example, the single device longitudinal detection distance is up to 22.5 meters, and the runway interface can be divided into five strips as shown in fig. 6 in the software deployment process.
As shown in fig. 7, the laser ranging equipment bracket comprises a horizontal turntable and a pitching turntable, the equipment is vertically installed, and the parabolic coverage of a laser ranging point on a runway is realized by adjusting the included angle theta 1 and the horizontal angle theta 2 between a laser beam and an absolute horizontal reference line through adjusting the pitching turntable and the horizontal turntable.
